It’s not an option when your business relies on refrigeration and temperature controlled storage.

Thousands of dollars in potential profits are at risk within minutes of a power outage. Is continuous power to the facility necessary? If you rely on it to regulate optimal conditions for inventory, have a contingency plan.

What’s yours?

Be prepared before an emergency occurs. Here’s what you need to know about choosing the right warehouse generator to keep things fresh.


Understand your wattage needs is the first step. If an unexpected power outage occurs, you don’t want to have to scramble around trying to determine your power needs.

There are two primary measurements for generator power.

Starting Watts

This is also referred to as peak power, max watts, or startup power. This is the amount of power, in watts, required for the initial startup of appliances (refrigerators, freezers, etc.). It is also a measure of the wattage required while the appliance is running at full capacity.

Running Watts

Sometimes also described as continuous watts, running power is the wattage any appliance requires to operate continuously under normal loads.

Calculating Wattage

It’s important to know the amps and voltage needs of the facility. Use these to calculate the wattage required to use a warehouse generator.

The basic calculation is amps multiplied by volts.

Look at the circuit breaker handle for an amp value. This is the max amps a circuit breaker can withstand.

For large facilities, knowing this information ahead of time is imperative to handling emergency situations quickly and effectively.

Do you live in an area where power outages are likely to occur i.e. hurricane season? Have a professional perform an initial site survey before an emergency happens.

Emergency Standby Power (ESP)

There are four rating categories used to determine the specific applications for generators. They are Prime Power (PRP), Limited-Time Running Prime (LTP), Continuous Power (COP), and Emergency Standby Power (ESP).

ESP rated generators supply emergency power to a building during utility outages. They have a higher load factor so they last until power is restored.

Look for a warehouse generator rental company that will refuel whenever necessary.

Warehouse Generator Safety

Some basic safety tips for running a generator:

  • Position the generator on a level surface
  • Avoid overfilling the fuel tank
  • Always turn off a generator and allow the engine to cool before adding fuel
  • Keep fuel-filled generators away from any type of flame. This includes pilot lights and sparks.
  • Make sure the generator is properly grounded before turning it on
  • The generator needs to have a minimum of five feet clearance on all sides
  • Have generators inspected at regular intervals
  • Use the generator only for powering the equipment it was intended to power; overloading can cause serious problems, including generator failure

Be Prepared

It’s normal to take electricity for granted. You flip a switch and expect the lights to turn on, or the air conditioner to start cooling. But, as many realized during the recent wave of hurricanes, outages can happen unexpectedly.

Make sure your operation is ready when such an emergency occurs.
